windowfunctions.jl's Introduction

WindowFunctions

Motivation

In both digital filter design and spectral estimation, the choice of a windowing function can play an important role in determining the quality of overall results. The main role of the window is to damp out the effects of the Gibbs phenomenon that resulted from truncation of an infinite series.

Methods

Function Window Type
barthann Modified Bartlett-Hann
bartlett Bartlett
blackman Blackman
blackmanharris Minimum four-term Blackman-Harris
bohman Bohman
cheb Chebyshev
flattop Flat top weighted
hamming Hamming
hanning Hann (Hanning)
nuttall Nuttall-defined minimum 4-term Blackman-Harris
parzen Parzen (de la Vallée Poussin)
rectangular Rectangular
triangular Triangular
tukey Tukey (tapered cosine)
taylor Taylor
gauss Gaussian
kaiser Kaiser
enbw Equivalent noise bandwidth

Installation

To install the released stable version, run

using Pkg
Pkg.add("WindowFunctions")

Example

using Plots
using WindowFunctions

kaiser5(N; dtype::DataType=Float32) = kaiser(N, 5.0, 10, dtype=dtype)

winlist = [barthann,
           bartlett,
           blackman,
           blackmanharris,
           bohman,
           flattop,
           hamming,
           hanning,
           nuttall,
           parzen,
           rectangular,
           triangular,
           gauss,
           tukey,
           kaiser5]

for win in winlist
    plot(win(256, dtype=Float32),
         label=string(win),
         fillrange = 0,
         fillalpha = 0.3,
         show=true)
    ylims!(-0.13,1.18)
    xlims!(1-20,256+20)
    sleep(1)

Do you have any suggestions?

Hi,

please check your example code, the execution fails on my computer with the following error message.

Regards,

Compatibility to RC

Please could you have a look? - It seems, as if there is a compatibility issue with your package and Julia v1.9.0RC2:
